A simple hello world

[abdul]

I just downloaded the latest version of nasm but the "Hello World!" code in the FAQ doesn't work now. It gives me some kind of error message on Line #1. I just restarted doing assembly after a few months and I remember I was able to run some asm code using nasm but can't now. Any idea on what would the starting lines for Nasm (eg .Stack, .Code, etc) and where to put the actual code?

[mmiill]

type your program here and i will see if i can halp u but whole program please

[abdul]

    jmp    start
Message1    db "Hello World!$"

start:
    mov    ah, 09h
    mov    dx, offset Message1
    int    21h

    mov    ax, 4c00h
    int    21h 

[mmiill]

.modal small
.stack 100h
.data
rec db 'zdravo narode(hello world)$'
.code
start:
mov dx,@data
mov ds,dx
mov dx,offset rec
mov ah,9h
int 21h
mov ah,4ch
int 21h
end start

[abdul]

Doesn't work - gives me errors (starting from line #1) saying something like "attempt to define a local label before any non-local labels". Also gives me an error message on line 9 saying "Comma or end of line expected" and another error on line #14 saying "parser: instructions expected".

[mmiill]

i think we don't use the same version of asm or something like that

try again

jmp start
rec db 'ererrw$'
start:
mov dx,@data
mov ds,dx
mov dx,offset rec
mov ah,9h
int 21h
mov ah 4ch
int 21h


or something like this it should works

[abdul]

Still doesn't work.

[mmiill]

try to download this version of asm and 100% it will works

[mmiill]

well i sugest u to download some other version of asm becouse seample which i gave u is fine and it works very good on my conm

here some code from my program:

.model small
.stack 100h
.data
poruka db 13,10,'usa$'
sifra db 'minja$'
duz equ $-sifra
text db 13,10,'Enter password:$'
poz db 13,10,'HMHMHM$'
.code
start:
mov dx,@data
mov ds,dx
poc:
mov dx,offset text
mov ah,9
int 21h
mov bx,0
mov cx,0
ponovi:
xor ax,ax
mov ah,8
int 21h
cmp al,13
je lab1
cmp al,sifra[bx]
jne lab2
ispis:
mov dl,'*'
mov ah,2
int 21h
inc bx
jmp ponovi
lab2:
mov cx,1
jmp ispis
lab1:
cmp cx,1
jne p2
p1:
lea dx,poruka
mov ah,9
int 21h
jmp poc
p2:
cmp bx,duz-1
jne p1
lea dx,poz
mov ah,9
int 21h
kraj:
mov ah,4ch
int 21h
end start


tell me if it works

tell me if it works

There is no other version of asm. I think you are talking about the assembler. Right now I am using NASM 0.98 but I'll try to use TASM and see if that works.

[mmiill]

i work whit that kind of asembller TASM i don't know what is NASM and all programs from upside going to work if u download TASM

end i think u gonna find good version of TASM but if you need help just say

good luck

[CodeRonin]

This is TASM, so it certainly won't work in Nasm...
However, I wouldn't work with:
mov dx, offset rec
I'd use
lea dx, rec

It's the newer and better way.

[mmiill]

ok lea is better than mov dx,offset text , but his question was about mov etc.

do u know something about programing whit PORT ......??

[snakeeyes1000]

type this in. I had the same problem too. Hope this helps.

section .data

db txtString "Hello World$"

section .bss

section .text

@start:

mov dx,txtString
mov ah,9h
int 21h

@end:
mov ah,4Ch
int 21h

[Darkwraith]

mmiill, that code listing works in NASM?
